In today’s competitive industrial landscape, reducing operational costs while achieving sustainability goals is a necessity, not a choice.
However, one of the biggest barriers for industries adopting solar energy has been the upfront capital investment.

At GRE Renew Enertech Limited, we remove this barrier by offering two progressive models: the OPEX (Operational Expenditure) EPC Model and the RESCO (Renewable Energy Service Company) IPP Model.
Both models allow industries to harness solar power without any upfront investment, enjoy immediate savings, and contribute to a greener future.

Understanding the OPEX Model (EPC)

The OPEX model is a game-changing financial structure where industries can install solar power plants without purchasing or owning them.
In this setup:

  • GRE finances, installs, commissions, and maintains the solar plant.
  • The industry simply pays for the electricity consumed at a pre-agreed tariff, which is significantly lower than grid power rates.
  • Ownership of the asset remains with GRE throughout the contract period.

In essence, industries shift from owning infrastructure to purchasing energy — solar as a service.

Advantages of the OPEX Model:

  • Zero upfront CAPEX: No large capital blocked in non-core assets.
  • Immediate savings: Lower energy bills from day one.
  • No maintenance burden: GRE handles full O&M (Operations & Maintenance).
  • Scalable: Easy to expand capacity as business needs grow.

Understanding the RESCO Model (IPP)

The RESCO model is an advanced variant of the OPEX structure, where GRE operates as an Independent Power Producer (IPP).

  • We invest in, own, and operate the solar plant.
  • A Power Purchase Agreement (PPA) is signed with the client, typically for 10–25 years.
  • The client only pays for the units of power consumed.

Here, industries don’t buy panels — they simply buy clean, affordable solar power over a long-term agreement, ensuring cost predictability.

Advantages of the RESCO Model:

  • No ownership hassles: Complete peace of mind.
  • Performance guarantee: GRE ensures high-efficiency generation.
  • Cost certainty: Lock your energy costs for decades.
  • Green branding: Enhance corporate ESG and CSR image.

Why OPEX and RESCO Are Perfect for Industries Today

With rising grid tariffs, carbon taxation, and customer demand for sustainable supply chains, industries need solutions that are:

  • Cost-effective
  • Asset-light
  • Risk-free

Both the OPEX and RESCO models offer the perfect blend of flexibility, savings, and sustainability, especially for large-scale industries such as manufacturing, textiles, pharmaceuticals, and chemicals.
